multi-path channel model

A multi-path channel model describes how a wireless signal reaches a receiver through multiple paths due to reflections, diffractions, and scattering caused by obstacles like buildings or terrain. Instead of traveling in a direct line, the signal splits and takes different routes, arriving at slightly different times and with varying strengths. These multiple signals combine at the receiver, which can cause interference, leading to fluctuations in signal quality and data rates. Understanding this model helps in designing better communication systems that can handle such variations and improve reliability.
